MARINE VESSEL.

SPECIFICATION forming part of Letters Patent No. 293,793, dated February19, 1884,

Application filed July 19, 1883.

Z) aZZ whom it may concern.-

Be itknown that I, AMEDEE M. G. SnBILLoT,

of Paris,France, have invented a new and Improved Marine Vessel, ofwhich the following is a full, clear, and exact description.

The objectofmyinvention is to provideanew and improved marine vessel ofa novel shape, which vessel is to be so constructed that a very highspeed can be obtained with the greatest possible economy of motivepower, and which vessel is practically unsinkable; and to this end theinvention consists in the peculiar construction and arrangement ofparts, all as here inafter fully described and pointed out in theclaims.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side view of my improved marine vessel. Fig. 2 is aplanview of the same. Fig. 3 is a crossscctional elevation of the same. Fig.4 is a front end view of the same.

The vessel is constructed with three longitudinal compartments, A B B,of which the former is a middle compartment and the last two are sidecompartments, the parting-walls extending from the bottom of the hull tothe deck. The middle compartment is made very narrow in relation to itslength, and is made very sharp at both ends. The middle compartmentalone would form a vessel of extremely sharp lines, but would have nostability, capacity, or strength.

For the purpose of making the vessel wider and giving it the desiredstrength, capacity, and stability, the side compartments, B, are formedon the sides of the central compartment A. The said compartments Bgradually increase in width from the front of the vessel to about themiddle of the same, and then extend to the stern at a uniform width, andare rounded at the stern, as shown. The side compartments, B, are madefiat-bottomed, and do not extend down as far as the bottom of the middlecompartment, A, so that that part, A,

of the middle compartment projecting below the bottoms of the sidecompartments, B, forms an enlarged or widened keel portion of the entirevessel. The vessel is also to be divided into compartments by a seriesof transverse (No model.)

partitions or bulk-heads. The ship has a very easy motion, as thepointed bow of the center compartment, A, cuts the water easily, and theforemost parts of the compartments B slide smoothly on the water andpenetrate it easily without repelling it. The lines obtained are veryfine, and yet the vessel has a broad bearing-surface, and thus has greatstability, on account of the flat bottoms of the compartments B B. Thetop of thefront of the compartment A is tapered from the front upward,to form a prow to cut the water. The vessel is much safer in case of acollision than other vessels, for if the prow of my improved vessel runsinto another vessel, the prow only will be injured, and-as that is verynarrow much water cannot accumulate in it; and if the front compartmentis filled with water the front of the vessel will be drawn downward buta short distance, as the bulk or larger part of the vessel is toward therear. The transverse partitions or bulkheads prevent the water fromflowing into the rear part of the vessel. If the side of the vessel isstruck, only one of the side compartment-s, B,will be torn open, as thesame presents sufficient resistance to prevent the prow of the strikingvessel cutting completely through it and striking the main hull A.

Sailing-vessels, screwnopellers, and side or stern wheel steamers can beconstructed in the manner described. Screw-propellers, although ingeneral use on ocean-steamers, are not as effective, if very great speedis to be obtained, as wheels are; but the difficulty has been thatside-wheel steamers had to be built very broad, and often the wheelswere not properly immersed, especially in rough seas. In my improvedvessel the wheels D can be arranged in the rear parts of the sidecompartments, B, the paddles projecting from the bottoms of thecompartments B, as shown. The wheels will always be immersedsufficiently, as the bottoms of the side compartments are alwaysimmersed. I

I do not abandon or dedicate to the public any patentable feature setforth herein and not hereinafter claimed, but reserve the right to claimthe same, either in a reissue of any patent that may be granted uponthis application, or in other applications for Letters Pat ent that Imay make.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A marine vessel divided into three longitudinalcompartments by partitions or walls extending from the bottom of thehull to the deck, the side compartments being formed on the sides of themiddle compartment and the latter projecting below the sidecompartments, as set forth.

2. A marine vessel constructed with three longitudinal compartments, themiddle compartment being tapered toward the front and rear, and the sidecompartments gradually increasing in widthfrom the front of the vesselto about the middle, and then running at a uniform Width toward the rearof the vessel, substantially as herein shown and described.
